PUMP.

` To all whom t may concern:

Be it known that I, PHILIP H. SHUE, a citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Pumps, of which the following is a specilication.

This invention relates to improvements in pumps and its principal object resides in the provision of a mechanism which, by the use of air under compression, will raise water from deep wells and other inaccessible places and deliver it in a substantially continuous stream at a point of higher elevation.

My invention includes to this end, a system of coperative elements, one of which is submerged in the fluid to be raised while the others are actuated by the flow and weight of the elevated water to direct a current of air under compression alternately into separate compartments of the submerged element.

inasmuch as the operative parts of the mechanism are installed above the surface of the water and separate from the conduits through which the fluid is conducted from its source to its point of delivery, they cannot possibly be affected by sand and other solids contained in the water and this feature in connection with the simplicity of construction of the apparatus, render the invention serviceable in places where skilled mechanics are not readily available and the water elevating devices are operated, adjusted and if necessary repaired by persons inexperienced in the construction of machinery.

An embodiment of my invention is illustrated in the accompanying drawings in the various views of which like parts are similarly designated and in which- Figure 1 represents a sectional elevation of the apparatus. Fig. 2, a vertical elevation partially in section along the line 2-2 Fig. 1. Fig. 3, a plan View of the uppermost element shown in the preceding figures. Fig. 4, a transverse section along the line 4-4 Fig. 2. Fig. 5, a similar section taken along the line 5-5 Fig. 2, and Fig. 6, a section taken along the line 6-6, Fig. 1.

My improved pump comprises, essentially, three coperative elements respectively des- Speecation of Letters Patent.

ignated in the drawings by the letters A, B and C. The element A consists of a receiver 2 which in the operation of the invention is submerged in the body of water to be raised such as that contained in a well shown at D in the drawings. The receiver which is preferably made of sheet-metal and cylindrical in form is, by means of an upright partition 3, divided into two compartments 4 and 5 which are provided at their respective bottoms, with openings the flow through which is controlled by back pressure valves 6 and 7. The receiver 2 is furthermore provided with a delivery chamber 8 provided by a transversely disposed inclcsure which has in its bottom portion two valves 9 and l0 which control openings communicating respectively with the two compartments 4 and 5. A stand pipe 12 is connected at its lower end' with the delivery chamber 8 and two conduits 13 and 14 lead respectively from the compartments 4 and 5 to a valve-chest l5 comprised in the element B, which by means of pipe 16 communicates with a compressor, reservoir or other source of compressed air. The face-plate 20 of the chest 15 is provided with two inlet ports 17 and 18 which respectively connect with the conduits 13 and 14, and aninterposed exhaust port 24 through which the compartments of the receiver may be brought in communication with the atmosphere and which also serves to admit the means whereby the D-valve 19 slidably supported upon the plate 20, is operated.

The means above referred t-o consist of a bell-crank lever 21 which is fulcrumed upon a hanger 22, and whose arms connect respectively wit-h a central depression formed in the interior surface of the slide-valve and with the lower extremity of a pitman 23, which at its opposite end is pivotally attached to a lever 25 of the uppermost ele-` ment C which is designed for the automatic operation of the valve 19 by the flow and weight of the water discharged from the stand pipe 12. The lever 25 is composed of a rectangular frame which at a point intermediate its extremities is fulcrumed upon a supporting structure 26. Two buckets 27, of equal weight and capacity, are suspended from the arms of the lever at equal distances from its fulcrum and each of these buckets to move slidingly through slots cut in plates 30 which extend horizontally from the sup-V porting structure 26 and the said stems are l twisted so that when by downward movement of t-he buckets with which they are .4 associated, they are drawn through their respective slots, they will impart a rotary movement to their respectivevalves to either close or open the openings in the bottoms of the receptacles 27.

The ,lever 25 when at rest, is slantingly supported at one of its extremities upon one or the other of two stops which normally project into the arcual paths of said extremitieswhen moving about the fulcrum. Each of' these stops is composed of a lever 31 which isfulcrumedlupon a post 32v and which at its end engaged by the lever, is provided with an upwardly' movable trip 33 which while adapted to arrest the downward motion of the adjacent arm of thelever, will permit it to pass in the opposite direction without affecting' the lever of which the trip forms part. The opposite arms of the levers 31 carry poises 34, and

. stops secured to the posts 32 are provided to limit the movement of the` levers Vby gravitative action of said poises. The buckets 27 are made of suiiicient size to each receive the contents of' one of the compartments of the receiver 2 and the poises 34 are proportioned so that they will be overbalanced by the buckets when the latter are filled4 above a predetermined point. The connection between the end of the pitman 23 and the lever 25 is established at a point at one side of the fulcrum of the latter so that when the position of the lever is reversed, the slide valve 19 will be moved through the instrumentality of the bell-crank 21 to vary its position with relation to the ports in the plate upon which it is slidably supported. rlhe stand pipe 12 connects at its upper extremity with a branch 36 which projects horizontally above and in a vertical plane with the fulcrum of the lever 25, and which at a point intermediate its ends, has a downwardly directed nozzle 37. A trough 38 is pivotally mounted upon the branch 36 to receive the fluid discharged through the nozzle 37, and it extends, when at rest, slantingly ,in a direction opposite to that of the lever 25, A link 40 connects an end of the trough at one side of the plane of the axes of oscillation of the two members, with the arm of the lever at the opposite side of said plane so thatwhen the lever is moved about its fulcrum a similar movement in the opposite direction will be imparted to the trough 38. An inclined flume 39 disposed -ments comprised in the invention arranged Vas shown in the drawings, the receiver is lowered into the body of water to be raised and the valve-chest is brought in communication with the source ot' compressed air, the

degree of compression in which exceeds the weight of the column of fluid to be elevated. Presuming that the parts are in the position shown in Fig. 1, itwill be observed that the valve 19 has established communication between the compartment 5 of the receiver 2 and theatmosphere, while the opposite compartment 4 of the same is in communication with the interior of the valve chest which by means of the conduit 16 is continuously supplied with air under compression, the latter vflowing into the compartment forces the water contained therein through theV opening controlled by the valve 9, into the delivery chamber 8 whence it rises in the stand pipe 12. The intake valve 6 of the same compartment is at the same time held upon its seat by the pressure of water and air while the corresponding valve 7 which controls the inlet opening of the other compartment 5, is opened by the pressure of the water in which the receiver is submerged, and thus allows the water to enter the compartment until the position of the slide valve 19 is reversed. The last named action is discharged through the nozzle 37 into the `troughki38 through which it flows into the bucket 27 at the upper end of the lever25. lVlien the bucket is in this position the openings in its bottom are closed by the valve 28 and the water is discharged thereinto from the trough 38 until its level has reached a determinate point, when the combined weights of the bucket and its contents will over-balance the poise at the end of the lever 31 upon which the lever 25 is supported. The latter is in consequence moved about. its fulcrum by the gravitative influence of the loaded bucket, until its position is reversed. During the downward motion of the loaded bucket, the openings in its bottom are opened by the movement of its valve induced by the longitudinal motion of its twisted stem through the slot in the respective plate 30 and its contents are thus discharged into the subjacent flume 39. Motion of the lever 25 about its fulcruin caused the slide valve 19 to reverse its position, through the instrumentality of the bell crank 21 and the pitman 23, and the position of the trough 38' is simultaneously reversed through the agency of the link 40.

izofIrv As a result of the above described actions the compartment 5 of the receiver 2 is now brought in communication with the source of compressed air, the compartment L connects with the atmosphere through the exhaust port 9.4L, the bucket at the opposite end of the lever 25 is in the raised position to receive the water iiowing through the trough 38 and the openings in the bot-tom thereof have been closed during the upward movement of the lever 29 through the slot in the respective plate 30. The conditions presumed at the beginning of the description of the operation of t-he invention are thus reversed and the flow of the water from the stand pipe will continue to effect alternate operations ot the elements and thus produce a substantially continuous flow oit' water, through the flume 39. q

Having thus described my invention what I claim and desire to secure by Letters- Patent is zl.
